How the estimates work
Cooked portions first
This calculator starts from cooked edible weight per guest — what actually lands on the plate. Raw purchase weight is calculated backward using your selected purchase yield.
Purchase yield (not just cooking shrinkage)
Smoked brisket typically yields about 45–57% from raw purchase weight to edible cooked meat, including trim and smoke loss. USDA food-service references cite roughly 46% purchase-to-plate yield for brisket in some preparations. We default to 50% as a practical midpoint within that range — adjust the slider if your trim or smoker runs higher or lower.
Adjust for your event
Side dishes, sandwiches, buffet service, and leftover preferences all change how much cooked brisket you need per guest. Use the meal type and leftover settings to match your setup.

Frequently asked questions
How much brisket per person?
Plan on about 4–8 oz of cooked brisket per adult depending on appetite. Six ounces is a common default for average eaters. Reduce the portion when brisket shares the plate with heavy sides or other proteins.
How much raw brisket for 10 people?
It depends on appetite, sides, and yield. For 10 adults at 6 oz cooked portions with side dishes and a 50% purchase yield, you need about 2.8 lb cooked brisket and roughly 6 lb raw to buy. Use the calculator above for your exact event settings.
How much brisket for 20 people?
For 20 adults with brisket as the only main protein, 6 oz cooked portions, and 50% yield, plan about 7.5 lb cooked and roughly 15 lb raw. With several side dishes, the raw total drops to about 11–12 lb at the same yield.
How much does brisket shrink when smoked?
Purchase-to-plate yield for smoked brisket is typically 45–57%, meaning you lose roughly half the raw weight to trimming, moisture loss, and fat rendering. Plan on about 50% as a practical default unless you know your trim style well.
What is the difference between cooked and raw brisket weight?
Cooked weight is the edible meat you serve. Raw weight is what you buy at the store. They are not equal — you generally need about 2 lb of raw brisket for every 1 lb of cooked brisket at a 50% yield.
How many people does a whole packer brisket feed?
A typical 12–16 lb whole packer yields about 6–8 lb cooked at 50% purchase yield. At 6 oz per person, that feeds roughly 16–21 adults before accounting for sides or leftovers.
Should I buy extra brisket for leftovers?
If you want extra brisket for sandwiches or next-day leftovers, add a 10–20% buffer using the leftover preference setting.
How is this different from the BBQ meat calculator?
This tool focuses only on brisket with deeper yield controls and packer sizing notes. Use the BBQ meat calculator when you are planning multiple proteins for the same event.
Data source
Portion and yield assumptions follow common BBQ event-planning references and USDA Food Buying Guide purchase-yield ranges. Price defaults come from the shared brisket entry in our beef dataset. All outputs are shopping and portion estimates only — not store guarantees or personalized guidance.
